Description

GetLogin implements an OpenID Connect authentication through OAuth 2 (implicit flow - client-side only).

Last project build hosted at getlogin.eth.

ETHCC2020 - Daniel Nagy: "Decentralized User Account Management"

Register your app in GetLogin smart contract

  1. Get last contract address from url: https://swarm-gateways.net/bzz:/getlogin.eth/xsettings

  2. Register as user with method createUser(usernameHash) where usernameHash is keccak256 hash of your username. Or pass if you already registered.

  3. Register application with method createApplication. Store application id which will return this method.

  4. Add allowed application urls (urls where your app is hosted) with addApplicationUrl

Inject GetLogin to your dApp

Add <script async src="https://swarm-gateways.net/bzz:/getlogin.eth/api/last.js"></script> to <head>

Init:

window.getLoginApi.init(appId, 'https://swarm-gateways.net/bzz:/getlogin.eth/', redirectUrl)
.then(data => {
    console.log(data);
});

where appId is your app id stored in step 3 of registration app instruction, redirectUrl is your app url.

Call methods: window.getLoginApi.getUserInfo().then(data => alert(JSON.stringify(data))).catch(e => alert(e));

Call dApp contract methods

Set contract ABI: window.getLoginApi.setClientAbi(abi);

Call getNotes method which defined in your dapp contract:

window.getLoginApi.callContractMethod(address, 'getNotes', usernameHash)
.then(data => {
    console.log(data);
})
.catch(e => {
    console.log(e);
});

address is your dapp address

Send transaction to your dapp contract:

window.getLoginApi.sendTransaction(address, 'createNote', noteText, {resolveMethod: 'mined'})
.then(data => {
    console.log(data);
})
.catch(e => {
    console.log(e);
});

address is your dapp address

createNote is your dapp method defined in contract

One important param is resolveMethod. Values of this param can be:

'mined' - fired when tx sent and mined (slow)

'transactionHash' - when tx sent (fast)
